I've implemented the 3x2 switch mod per www.deviationtx.com/forum/7-development/...tion?start=100#22231

I have also set extra-switches=3x2 in hardware.ini.

I am using the most recent nightly build (v4.0.1-92e1705).

Now, my left trims (both horizontal and vertical) and my Switch A up position does not work.

All connections seems to be good. There is no short that I can see.

Did I fry something while soldering in the wires? Any ideas of what to check?

Is it possible to remap the right trims to adjust the left trims when Switch A is in the down position?

Thanks!

Did you remember to add the 4 diodes in the correct orientation?

Yes, diodes are installed at all 4 terminals. They are oriented with the stripe closest to the switch. The current flows into the switch as verified by a multi-meter.

I fixed the issue with the trim.

When I soldered the "brown" wire (the one that connects to the middle pin on the right), I had melted the solder that attaches to the trace on the PCB.

I was able to re-solder making contact with the trace and got it working again.
